Steven Dewall/Getty Images(NEW YORK) -- We don't know if they'll be wearing ski jackets from the thrift shop, but Macklemore & Ryan Lewis will be performing a free concert at the 31st Annual Burton U.S. Open Snowboarding Championships at Colorado's Vail Mountain. The duo's show on March 1 will kick off a series of free concerts at the outdoor event. The pair is set to hit the stage at 6 p.m. MT after the the day's slopestyle finals.

On Wednesday, Macklemore took to Facebook to thank fans for helping the "Thrift Shop" video reach 100 million views on YouTube, posting a picture of himself on stage this week in Melbourne, Australia. The song is spending its fourth straight week atop the BillboardHot 100.
